Noise From My Top End Any Ideas

Featured Replies

hi everybody i have a Noise from my top end on my montesa 4rt 2006 i have ruled out the tappets as its a tapping sound what ealse could it be there is a little movement in the cam shaft?

clue in the tapping noise.sounds like tappets.there should be no play in camshft,poss due to not change oil regular.

Gday, how is the cam chain? You shouldnt be able to lift it off the sprocket. Also, that motor in the CRF does have gudgeon issues. They are meant to be replaced every 15 hours or something like that if I remember correctly. Have a look into these areas.

Cheers,

Stork.

yes i dont think the last owner changed the oil ever...... thanks for your idias i will look in to them and let you know

it seems to me that when you ask a question on here ,out of courtesy or manners, you reply to answers .

given your post history , it would seem you show neither !

with either given you would get more help !!!
